Hey peeps. Need to know where to get the negative ignition signal for the lockoff when running a high voltage msd ignition. I cant use the negative off the coil because the voltage is too high and will fry the lockoff unit. The 6btm had a tchometer out port that outputs a 12v square signal at 20% duty cycle will that work?

Wind the lock off wire around your coil lead and wrap tape around it all. Works great.

are you joking?

No. Works fine.
